Day per Ten Thousand 

Lu Li transmigrated and became an apprentice in a Demonic sect. He was also given the Martial Art System.
He could automatically cultivate any technique as long as he learned it.
But.
[Your Blood-Devouring Demonic Technique is feeling sad as it has not absorbed human blood. Cultivation level decreased.]
[Your Heart-Shattering Palm Technique is not satisfied as you have only been killing animals. No progress with its cultivation level.]
[Your Seven Kills Fist Technique is very dissatisfied with your kind heart. Cultivation level decreased.]
[Your Ghostly Steps Technique does not have enough energy as you have not fused with the soul of any ghosts or spirits. No progress with its cultivation level.]
......
Lu Li had no other choice when he read the system notifications.
Thus, he started to cultivate orthodox techniques in the Demonic sect.

Was Demonic Devil about to undergo the tribulation?

The Lightning Tribulation was so terrifying that it could even pierce through the Demons Cave?

Could it be... that Demonic Devil was going to die under the Lightning Tribulation?

At this moment, a huge black hand appeared in the sky, blocking the sky and the sun. With a light sweep, it wiped out all the lightnings in the sky.

The entire sky of the Demons Cave was normal again.

"Run! Let's go somewhere else to watch our Master become a Demigod!" Bai Jinfei said with a solemn expression as he waved his hand.

A stream of ghostly qi gushed out from Bai Jinfei's sleeve. It swept up both him and Lu Li. They quickly headed toward the south.

After traveling at lightning speed, the two of them rushed to an entrance. They passed through the blue barrier and exited the cave.
